HOPPER-BOTTOIVI FREIGHT-CAR.`

SPECIFICATION forming part of Letters Patent No. 741,250,`dated October13, 1903. Application filed June 6, 1903. Serial No. 160,386. (Nomodel.)

To all whom it may concern:

Beit known that I, HERBERT R. KEITHLEY,

a citizen of the United States, residing at Chicago, in the county ofCook and State of Illinois, have invented new and useful Improvements inHopper-Bottom Freight-Cars, of which the following is a specication.

This invention relates 'to a steel hopperbottom car built up of platesand commercial rolled shapes, and more particularly to a car vof thetype shown in United States Letters In the accompanying drawings,consisting of iive sheets, Figure 1 is aside elevation of one-half of acar embodying the invention. Fig. 2 is a central' longitudinal sectionthereof. Fig. 3 is a horizontal section thereof in line 3 8, Fig. 2.Fig. i is a transverse vertical section, on an enlarged scale, in line4: 4, Fig.

2. Fig. 5 is a view on an enlarged scale, one half in end elevation andone half in transverse section, inline 5 5, Fig. 2.

Like letters of reference refer to like parts,

in the several figures.

Brieiiy stated, the car comprises, like the car of my said patent,holsters and center" sills arranged in their usual relation, sides inthe form of deep-trussed plate-girders, which are secured to theholsters and constitute the main supports hetween'the holsters for theweight of the car and its load, side hopperplates secured to anddepending below the lower flanges of the plategirder sides, and inclinedend and intermediate hopper-bottom plates which connect the plategirdersides and side hopper-plates.

Fach plate-girder side of the car consists of a vertical central webplate A, vertical end web-plates B, and upper and lower flanges orchords C and D, preferably formed by angle-hars riveted to theweb-plates. The angle-bar forming the lower flange is arranged outsideof the weh-plates with its horizontal ilange projecting outwardly. Thecentral weh-plate A is arranged in a vertical plane inside of the planeof the end web-plates B, with its ends overlapping and riveted to thevertical inner ends of the end web-plates,

thus leaving a space between the central web-plate and the lowerflange-angle D for the reception of the hopper side plates, ashereinafter described. The car side is also preferably provided with atruss-chord E, struts or ties e, diagonal braces e', and wehstiffenersc2, riveted to the web-plates, as eX- plained in my said patent. Inorder to better stiften the side against lateral bulging or deiiection,the upper truss-chord is formed by a Z-bar arranged with its webhorizontal and its inner vertical flange riveted to the webplates.Suitable filler-plates are preferably arranged between the upper iiangeof the girder and the end weh-plates B and between the truss-chord E andthe central web-plate A to avoid bending of the flange-angle andtruss-chord laterally.

F represents one of the bolsters, which are arranged in the usualrelation and are secured at their ends to the plategirder sides of thecar, and G represents the center sills, which extend from -end to end ofthe car,

passing through the holsters and between the Aplates extending below thelower. iiange of the sides and having their upper horizontal edgeslocated between and riveted to the central web-plates and lowerflange-angles D of the car-sides.

The bottom of the car has end and intermediate inclined portions. Theend inclined portions are formed by longitudinal side and central bottomplates I I', which are riveted together at their longitudinal meetingedges. The side bottom plates I extend down on opposite sides of thecenter sills and are secured at their outer edges to the weh-plates ofthe girder sides and up right outside hopperplates by anglehars i or inany other usual manner. The central bottom plate I extends from end toend of the car, having a central horizontal portion il', which rests onand is riveted to the upper flanges of the center sills, forming a coverand connecting-plate IOO for the latter and serving to securely connectthe center sills to the bottom of the car. The intermediate inclinedportions of the bottom are formed by inclined plates I2, which convergeupwardly toward the center of the car, and hopper-doors I3, hinged attheir upper edges to the lower edges of the intermediate plates I2. Thelatter extend from side to side of the car and are secured .to theside-girder web-plates and outside upright hopper-plates by angle-barsi2 or otherwise. The intermediate plates I2 are slotted at their lowerends for the passage of the center sills.

K represents inner upright hopper -plates arranged at opposite sides ofthe center sills and preferably secured to the'inclined side andintermediate bottom plates I and I2 by angle-bars if.. The inner uprighthopperplates are connected at the upper ends by an arched plate 7c overthe center sills. The outer upright hopper side plates only extend tothe inner ends of the end web-plates B of the car-sides, and theopenings thus left at the outer sides of the hopper beneath the endweb-plates B are closed by vertical triangular patch-plates k2, arrangedinside of and riveted to the outer upright hopper side plates, lowerflange-angles of the car-sides, and angles i', connecting the uprightouter side and bottom plates of the hopper.

y The vertical ends L of the car are formed in any usual or preferredmanner.

Each end sill of the car consists of a Z-bar M, arranged with its webhorizontal, its inner iiange extending vertically upward, and its outerflange extending vertically downward. The end portions of the web of theend sill rest upon the projecting ends n of the horizontal anges ofangle-bars N, Figs. 3 and 5, which are arranged inside of the endwebplates of the car-sides, with their vertical flanges riveted to saidweb-plates and the lower flange-angles of the sides. The anglebars Nextend from the end sill to the bolster and afford a very strong andrigid connection for the end sill.

posts O, connected at their lower ends to the end sills and loweriiange-angles of the sides and at their upper ends to the vertical endsof the car.

The operating mechanism for the hopperdoors is preferably constructed asfollows: The adj acentdoors on opposite sides of thecenter sill areconnected by a transverse flanged bar P, preferably an I-beam, rivetedto the lower free ends of the doors. Q represents a rock-shaft, of whichthere are two, arranged transversely beneath the end inclined portionsof the hopper. Each shaft is journaled in suitable bearings g on thecenter sills and outer portion of the hopper and is provided between thecenter sills with a long rock-arm QQ the free end of which extendsbeyond the adjacent hopper-doors when closed and is pivoted to one endof a link q2, which is pivoted at its other end to the transverse barconnecting the two hopper-doors. R represents a l door-operating leverwhich is pivoted on a stud or pin r, secured to the outside wall of thehopper. The lever is provided with a cam plate or portion having acurved face r and an inclined face r2, adapted to engage a shortrock-arm r3, secured to the adjacent end of the rock-shaft Q. Vhen thelever is in the position shown in Fig. 1, the curved face of the camengages the short rock-arm r3 and holds the latter and the rock-shaftstationary, with the doors closed. Vhen the lever is swung upwardly, asindicated by dotted lines in Fig. l, the short rock-armi"3 is released,and the doors swing open by reason of their weight. In the open positionof the doors the short rock-arm r3 bears against the inclined face ofthe cam, and when the latter is swung downwardly the inclined face ofthe cam forces the rock-arm r3 down, turning the rock-shaft and closingthe hopper-doors. After the inclined face of the cam turns the rock-armdown the curved face is moved into engagement with and holds therock-arm from movement.

-I claim as my inventiony l. In a car, the combination of a plategirderside, comprising web-plates arranged in different vertical planes, withtheir meeting ends lapped, and a hopper side plate having its upperportion arranged in the plane of one of said web-plates and beside andsecured to the other web-plate, substantially as set forth.
